GLUBEGINSURFACE(3gl)					  GLUBEGINSURFACE(3gl)

NAME
       gluBeginSurface, gluEndSurface - delimit a NURBS surface definition

C SPECIFICATION
       void gluBeginSurface( GLUnurbs* nurb )

       void gluEndSurface( GLUnurbs* nurb )

PARAMETERS
       nurb  Specifies the NURBS object (created with gluNewNurbsRenderer).

DESCRIPTION
       Use  gluBeginSurface  to	 mark the beginning of a NURBS surface defini‐
       tion. After calling gluBeginSurface, make one or more calls to gluNurb‐
       sSurface to define the attributes of the surface.  Exactly one of these
       calls to gluNurbsSurface must have a surface type  of  GL_MAP2_VERTEX_3
       or  GL_MAP2_VERTEX_4.  To mark the end of the NURBS surface definition,
       call gluEndSurface.

       Trimming of NURBS surfaces is supported with gluBeginTrim, gluPwlCurve,
       gluNurbsCurve,  and gluEndTrim. See the gluBeginTrim reference page for
       details.

       GL evaluators are used to render the NURBS surface as a	set  of	 poly‐
       gons.   Evaluator  state	 is  preserved during rendering with glPushAt‐
       trib(GL_EVAL_BIT) and glPopAttrib().  See  the  glPushAttrib  reference
       page for details on exactly what state these calls preserve.

EXAMPLE
       The  following  commands	 render a textured NURBS surface with normals;
       the texture coordinates and normals are also described  as  NURBS  sur‐
       faces:

       gluBeginSurface(nobj);
	  gluNurbsSurface(nobj, ..., GL_MAP2_TEXTURE_COORD_2);
	  gluNurbsSurface(nobj, ..., GL_MAP2_NORMAL);
	  gluNurbsSurface(nobj, ..., GL_MAP2_VERTEX_4);
       gluEndSurface(nobj);
